The International Balzan Foundation annually awards four prizes for
scientific and academic excellence. Each prize is valued at 1 million
Swiss francs (about $800,000), and winners are expected to earmark half
of the money for future projects to be carried out by young
researchers. The award ceremony will take place on Friday, Nov. 11, in
the Swiss Houses of Parliament in Bern.

The Grants were selected for "their remarkable long-term studies
demonstrating evolution in action in Galapagos finches," according to
the foundation. "The work of the Grants has had a seminal influence in
the fields of population biology, evolution and ecology. It is
generally regarded as the most significant study of evolutionary change
in the field that has been carried out in the last 30 years."

Peter Grant is the Class of 1877 Professor of Zoology and Rosemary
Grant is a senior research biologist at Princeton. For three decades,
the married couple have traveled to the Galapagos Islands off the coast
of South America to study the various species
of finch that influenced Charles Darwin when formulating his theory of
evolution. The Grants conduct research on how the finches have changed
as a result of dramatic climatic differences.

Both are interested in the interplay of genetics, ecology and behavior,
and especially in the question of why and when one species separates
into two. In 1991, their joint publication, "Evolutionary Dynamics of a
Natural Population: The Large Cactus Finch of the Galapagos," earned
the Wildlife Publication Award of the Wildlife Society. They also
received the E.O. Wilson Prize of the American Society of Naturalists
in 1998, the Darwin Medal of the Royal Society of London in 2002 and
the Grinnell Award of the University of California-Berkeley in 2003.

The Grants are members of the American Academy of Arts and Sciences and the General Assembly of the Charles Darwin Foundation.

Since 1961, 106 scientists, scholars, artists and institutions have
been honored with the Balzan Prize, including Mother Teresa, the Nobel
Foundation and Paul Hindemith. Previous Princeton winners include
Charles Gillispie, the Dayton Stockton Professor of History Emeritus,
and Anthony Grafton, the Henry Putnam University Professor of History.
